I still have not notice any kind of studdering in my games running SLI ,Two cards are not loud at least the Asus version is not. I cant hear it, even when turned to a 100% it just barely noticeable,if I get close enough to it.But if you just want one card then there is no other solution.The Titan is a super fast card for just a single GPU.Two GTX-680's will be faster in games ,but that would still be around $1000 ,plus the GTX-Titian is only 15% to 20% slower.The Titian will use less power and take up less space.
